PHP+MYSQL+AJAX实现每日签到功能...

一、web前端及ajax部分
文件index.html
<html>
<head>
<meta http-equiv=Content-Type content="text/html;charset=utf-8">
<title>PHP+AJAX+MYSQL实现每日签到</title>
<script type="text/javascript" src="js/jquery.min.js"></script>
<script type="text/javascript">
　　//page load get num
　　$(window).ready(function(){
　　　　doGetDays();
　　});

//get sign days
function doGetDays(){
　　$.get("/sign.php?do=getDay",{},function(data){
　　　　$("#days").html(data);
　　});
}

//do sign
function doSign(){
　　$.get("/sign.php?do=sign",{},function(data){ <br>　　　　if(data==1){
　　　　　　alert("sign success!");
　　　　　　window.location.href='/';
　　　 }else if(data==2){
　　　　　　alert("already sign today! next tomorrow!");
　　　 }
});
}
</script>
</head>

<body>
<a style="cursor:pointer;" onclick="doSign();">签到<span>连续签到<span id="days"></span>天</span></a>
</body>
</html>

二、PHP后端处理部分
sign.php文件
<?php
if ($_GET['do']=='getDay'){
$db=new mysqli('localhost','root','123456','sign');
$uid=2; $getDay="SELECT `signdays` FROM `user` WHERE `id`= {$uid}"; $day=$db -> query($getDay); $days =$day -> fetch_array(MYSQLI_ASSOC); echo $days['signdays'];
}

if ($_GET['do']=='sign'){
　　$db=new mysqli('localhost','root','123456','sign');
　　$uid=2;
$time=time();

//check sign today
$todayBegin=strtotime(date('Y-m-d')." 00:00:00");
$todayEnd= strtotime(date('Y-m-d')." 23:59:59");
$checkSignSql="SELECT * FROM `sign` WHERE `uid` = {$uid} AND `dateline` < {$todayEnd} AND `dateline` > {$todayBegin} ";
$checkSignToday= $db -> query($checkSignSql);
$checkSign = $checkSignToday -> fetch_array(MYSQLI_ASSOC);

　　if (empty($checkSign)){
$sql="SELECT * FROM `sign` WHERE `uid` = {$uid} ";
$return = $db -> query($sql) -> fetch_array(MYSQL_ASSOC);

//check sign table exist uid record
if (empty($return)){//no
　　　　　　$insertSql="INSERT INTO `sign` (`uid`,`dateline`) VALUES ('{$uid}','{$time}') ";
$insert = $db -> query($insertSql);
$updateSignSql="UPDATE `user` SET `signdays` =1 WHERE `id` = {$uid} ";
　　　　　　$db -> query($updateSignSql); echo 1;
　　　　}else{　　　　　　// check is continuous ? reset with login set signdays as 0 !!!!!
$yesterdayBegin= strtotime(date("Y-m-d",strtotime("-1 day"))." 00:00:00");
$yesterdayEnd= strtotime(date("Y-m-d",strtotime("-1 day"))." 23:59:59");
$checkContinuSql="SELECT * FROM `sign` WHERE `uid` = {$uid} AND `dateline` < {$yesterdayEnd} AND `dateline` > {$yesterdayBegin}"; $checkContinuYesterday = $db ->query($checkContinuSql) -> fetch_array(MYSQL_ASSOC);

if (!empty($checkContinuYesterday)){
$replaceSql="REPLACE INTO `sign` (`uid`,`dateline`) VALUES ('{$uid}','{$time}') ";
$replace=$db -> query($replaceSql);
$updateSignSql="UPDATE `user` SET `signdays` = `signdays` + 1 WHERE `id` = {$uid} ";<br>
$db -> query($updateSignSql); echo 1;
}else{
}
}
}else{
echo 2;// allready sign.
}
?>

三、Mysql数据库部分
CREATE TABLE IF NOT EXISTS `sign` (
`uid` int(11) NOT NULL,
`dateline` varchar(10) COLLATE utf8_bin NOT NULL, PRIMARY KEY (`uid`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_bin;

INSERT INTO `sign` (`uid`, `dateline`) VALUES (1, '1389072071'), (2, '1389072735');

CREATE TABLE IF NOT EXISTS `user` (
`id` int(11) NOT NULL AUTO_INCREMENT COMMENT 'USERID',
`username` varchar(35) COLLATE utf8_bin NOT NULL COMMENT 'username',
`signdays` int(11) NOT NULL COMMENT '签到天数', PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_bin AUTO_INCREMENT=3 ;

INSERT INTO `user` (`id`, `username`, `signdays`) VALUES (1, 'ggbound', 4), (2, 'other', 1);
